Frequently Asked Questions Does the DNA filter offer the same level of protection as the OEM filter? Yes, and even better. DNA filters have a minimum filtration efficiency of 98% (ISO 5011 test). Good quality OEM paper filters range from 97% to 99%, while foam filters range from 92% to 97%. What is filtration efficiency? Filtration efficiency is the amount of dirt the filter can retain to effectively protect the engine. For example, for every 100 grams of dirt received, the DNA filter retains 98-99 grams, even for fine particles down to 5 microns. Can I use the DNA filter for off-road use? Yes, DNA has developed a unique filter media, perfect for off-road use. During the 2011 Dakar Rally, an official Aprilia 450 Rally competed with a DNA filter with excellent results compared to foam filters, without any dust passing through and using only one filter per day compared to the 2 or 3 needed with foam. How often should I clean my DNA filter? Maintenance intervals depend on the operating environment. Once a year or every 15,000-30,000 km is recommended. A simple method to check if the filter needs cleaning is to see if the wire mesh on the dirty side is still visible: if so, the filter can continue to be used.
